A lockdown that affected Wethersfield schools Friday turned out to be a false alarm.

“At approximately 1:45 p.m. the entire school was placed on lockdown,” Supt. Shane Kazubowski said in a news release. “The lockdown was prompted by rumors that were circulating, and as a precautionary measure as the rumors were investigated, we went into lockdown.”

Police Chief Jim Dison said the rumor was that someone had a weapon on campus. Dison said no one claimed to have seen the weapon.

Kewanee police and the Henry County Sheriff’s Department responded, and after about 25 minutes “it was determined with 100 percent certainty that the rumors were false,” Kazubowski said.

“The decision to go into lockdown is always made with the students’ safety as the top priority, and the decision to go into a lockdown mode followed the procedures identified in our District Crisis Plan which was developed in cooperation with the Kewanee Police Department,” Kazubowski’s news release said.

“They did the right thing,” Dison said. “They heard a rumor and they called us. The kids’ safety was paramount.”
